290 MEMOIRS OF THE NUTTALL ORNITHOLOGICAL CLUB. 



272 [652] Dendroica aestiva (Gmel.). 

 Yellow Warbler. 



Abundant summer resident ; May 2 to September 26 ; average date of 

 arrival for six years, May 3 to 4. 



Eggs: May 27 to June 13.

 date, August 19th, 1878, records an adult female with breast devoid of feathers 

 as if recently incubating, shot in some bushes near the ocean at Magnolia. 



The interesting fact about this Warbler is that at the present day, at least,
